Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and more particularly, to a vehicle window deicing method, structure, device, vehicle, and storage medium in the field of vehicle technology. Background Art

[0002] Ice formation on vehicle windows is a very common phenomenon in autumn and winter. When ice forms on vehicle windows (e.g., front windshield windows), it causes inconvenience to users in driving the vehicle and affects their travel.

[0003] In the related art, the ice layer on the front windshield is mainly scraped off manually by the user using a plastic sheet or a knife, but it cannot guarantee that the ice layer on the front windshield is completely removed, resulting in low de-icing efficiency.

[0004] Therefore, how to improve the de-icing efficiency of car windows is an issue that needs to be urgently addressed. Summary of the Invention

[0005] The present application provides a vehicle window deicing method, structure, device, vehicle and storage medium, which can improve the deicing efficiency of vehicle windows.

[0006] In a first aspect, a vehicle window deicing method is provided. The method is applied to a vehicle, the vehicle including a target deicing device, the target deicing device including an air outlet device and a heating device. The method comprises:

[0007] Detect whether the vehicle's windows are frozen; if the windows are detected to be frozen, control the air outlet device and the heating device to operate so that the air flow ejected by the air outlet device is heated by the heating device and then ejects the hot air flow toward the windows.

[0008] In an embodiment of the present application, when ice is detected on the vehicle windows, the air outlet device and the heating device included in the vehicle's de-icing equipment can be controlled to operate, so that the airflow ejected by the air outlet device is heated by the heating device and then ejected as hot air toward the vehicle windows to de-ice the vehicle windows. This can avoid the low efficiency of manual de-icing of the vehicle windows by the user. Therefore, the above solution can improve the de-icing efficiency of the vehicle windows.

[0009] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes:

[0010] An air inlet temperature of air from an engine compartment of a vehicle in an air outlet device is obtained; and based on the air inlet temperature, whether to control a heating device to stop heating is determined.

[0011] In the embodiment of the present application, since the airflow from the air outlet of the air outlet device is derived from the engine compartment of the vehicle, the residual heat in the engine compartment can be used to de-ice the vehicle windows, thereby reducing the energy required by the heating device to heat the airflow ejected by the air outlet device, thereby reducing the energy consumption required for de-icing the vehicle windows.

[0012] In combination with the first aspect and the above implementations, in certain implementations of the first aspect, determining whether to control the heating device to stop heating based on the air inlet airflow temperature includes:

[0013] If the air inlet air flow temperature is greater than the first temperature threshold, it is determined to control the heating device to stop heating; if the air inlet air flow temperature is less than or equal to the first temperature threshold, it is determined whether to control the heating device to stop heating based on the internal temperature of the heating device.

[0014] In the embodiment of the present application, when the air inlet air temperature is greater than a first temperature threshold, it indicates that the air inlet air temperature meets the temperature requirement for de-icing the vehicle windows. Therefore, the heating device is no longer required to heat the air inlet air. Instead, the air outlet device can directly discharge the air inlet air toward the vehicle windows to de-ice the windows. Therefore, when the air inlet air temperature is greater than the first temperature threshold, the heating device is controlled to stop heating, thereby reducing the energy consumption required for de-icing the vehicle windows.

[0015] Furthermore, when the air inlet temperature is less than or equal to the first temperature threshold, it indicates that the air inlet temperature cannot meet the temperature requirements for window de-icing, and the heating device is required to increase the air inlet temperature. However, when the heating device is operating, the internal temperature is too high, which can pose a threat to the safety of the windows and the vehicle during the window de-icing process. Therefore, it is necessary to determine whether to control the heating device to stop heating based on the internal temperature of the heating device to ensure the safety of the windows and the vehicle during the window de-icing process.

[0016] In combination with the first aspect and the above implementations, in certain implementations of the first aspect, determining whether to control the heating device to stop heating based on the internal temperature of the heating device includes:

[0017] If the internal temperature is greater than the second temperature threshold, it is determined that the heating device is controlled to stop heating; wherein the second temperature threshold is greater than the first temperature threshold; if the internal temperature is less than or equal to the second temperature threshold, it is determined that the heating device is controlled to keep heating.

[0018] In this embodiment of the present application, when the internal temperature of the heating device exceeds the second temperature threshold, it indicates that the internal temperature of the heating device is too high. To avoid a significant difference between the temperature of the heated hot air flow and the current icing temperature of the vehicle window, which could cause the window to burst; or the excessively high internal temperature of the heating device could cause the heating device to spontaneously combust, posing a threat to vehicle safety. Therefore, when the internal temperature of the heating device exceeds the second temperature threshold, the heating device is controlled to stop heating (i.e., the air outlet device operates, but the heating device does not operate), thereby ensuring the safety of the windows and the vehicle during the window de-icing process.

[0019] Furthermore, when the internal temperature of the heating device is less than or equal to the second temperature threshold, it indicates that the internal temperature of the heating device is within the safe range. When the air inlet temperature is less than or equal to the first temperature threshold and the internal temperature of the heating device is less than or equal to the second temperature threshold, the heating device is required to raise the air inlet temperature to a level sufficient for vehicle de-icing. Therefore, when the internal temperature of the heating device is less than or equal to the second temperature threshold, controlling the heating device to maintain heating ensures normal window de-icing, thereby improving window de-icing efficiency.

[0020] In combination with the first aspect and the above implementations, in some implementations of the first aspect, the method further includes:

[0021] Obtaining the operating time of the air outlet device; controlling the vehicle's wiper device to operate a preset number of times each time the operating time reaches a preset operating time; wherein the wiper device is used to spray water on the vehicle windows and / or scrape ice off the vehicle windows.

[0022] In an embodiment of the present application, when it is obtained that the working time of the air outlet device reaches the preset working time, it means that the vehicle windows have been de-iced for a period of time, so that the ice layer can act as a lubricant after melting, thereby avoiding sharp ice crystals from damaging the wiper device and the vehicle windows, and directly starting the wiper device when the wiper device is frozen, which may cause damage to the wiper, thereby ensuring the safety of using the wiper device when the vehicle windows are frozen.

[0023] In combination with the first aspect and the above-mentioned implementations, in certain implementations of the first aspect, the hot air flow heated by the heating device is ejected toward the vehicle window through multiple nozzles in the target deicing device, and the multiple nozzles correspond to different areas of the vehicle window. The method further includes: if ice is detected on the vehicle window, detecting whether a target area on the vehicle window is frozen; wherein the target area is the area of ​​the vehicle window where the driver observes road conditions; and controlling the operation of the air outlet device and the heating device so that the air flow ejected by the air outlet device is heated by the heating device and then ejected as hot air toward the vehicle window, including:

[0024] If ice is detected in the target area, the flow rate of the hot air flow ejected by the target nozzle corresponding to the target area among the multiple nozzles is controlled to be greater than the flow rate of the hot air flow ejected by the non-target nozzles other than the target nozzle among the multiple nozzles; or, if ice is detected in the target area, the target nozzle is controlled to eject the hot air flow first, and then the non-target nozzles are controlled to eject the hot air flow until the target area is not frozen.

[0025] In an embodiment of the present application, when ice is detected in the area of ​​the vehicle window where the driver observes road conditions (which can be called the "target area"), the flow rate of the hot air flow ejected by the target nozzle corresponding to the target area among the multiple nozzles can be controlled to be greater than the flow rate of the hot air flow ejected by the non-target nozzle other than the target nozzle among the multiple nozzles; or, the target nozzle is controlled to eject the hot air flow first, until the target area is not frozen, and then the non-target nozzle is controlled to eject the hot air flow, so that the target area in the vehicle window is de-iced first; thereby ensuring the driving safety of the vehicle during the de-icing process.

[0026] In combination with the first aspect and the above implementations, in some implementations of the first aspect, detecting whether a vehicle window is frozen includes:

[0027] A target image of the vehicle window is captured by the vehicle's camera; if a foreign object is detected in the target image, the vehicle's outside temperature is obtained; if the outside temperature is less than a third temperature threshold, it is determined that the vehicle window is frozen; if no foreign object is present in the target image, and / or the outside temperature is greater than or equal to the third temperature threshold, it is determined that the vehicle window is not frozen.

[0028] In this embodiment of the present application, when a foreign object is present in a vehicle window image, the determination of whether the vehicle window is iced is made in conjunction with the vehicle's outside temperature. This can avoid errors that would occur if a single window image or a single outside temperature were used to determine whether the vehicle window is iced. Therefore, combining image and temperature can improve the accuracy of determining whether a vehicle window is iced.

[0029] In a second aspect, a vehicle window de-icing structure is provided, which includes: a blower having an air inlet and an air outlet; a heating device, one end of the heating device is connected to and communicated with the air outlet, and the other end of the heating device is directed toward the vehicle window; wherein the air flow out of the air outlet is heated by the heating device and sprayed toward the vehicle window.

[0030] In a third aspect, a vehicle window deicing device is provided. The device is configured for a vehicle, the vehicle including a target deicing device, the target deicing device including an air outlet device and a heating device; the device includes:

[0031] The detection module is used to detect whether the vehicle windows are frozen; the control module is used to control the air outlet device and the heating device to operate if ice is detected on the vehicle windows, so that the air flow ejected by the air outlet device is heated by the heating device and then ejected as hot air flow toward the vehicle windows.

[0032] In a fourth aspect, a vehicle is provided, comprising a memory and a processor. The memory is configured to store executable program code, and the processor is configured to retrieve and execute the executable program code from the memory, so that the vehicle executes the method of the first aspect or any possible implementation of the first aspect.

[0033] In a fifth aspect, a computer program product is provided, which includes: computer program code, which, when running on a computer, enables the computer to execute the method in the above-mentioned first aspect or any possible implementation of the first aspect.

[0034] In a sixth aspect, a computer-readable storage medium is provided, which stores a computer program code. When the computer program code runs on a computer, the computer executes the method in the above-mentioned first aspect or any possible implementation of the first aspect.

[0042] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0043] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0044] Figure 1 This is a schematic diagram of a vehicle window de-icing scenario provided in an embodiment of the present application.

[0045] For example, Figure 1 As shown, Figure 1 The vehicle 110 is included, and the vehicle 110 includes a front windshield window 111.

[0046] During the autumn and winter seasons, the front windshield 111 is prone to ice formation. To ensure vehicle safety, users are required to manually scrape the ice off the front windshield 111 using a plastic sheet or a knife. However, this manual de-icing method does not guarantee that the ice on the front windshield is completely removed, resulting in low de-icing efficiency. Alternatively, the vehicle's air conditioning system can be used to blow hot air onto the front windshield to melt the ice. However, if the vehicle's battery is low, the power required by the air conditioning system to de-ice the front windshield may prevent the vehicle from starting, affecting the user's travel.

[0047] In order to solve the problem of low deicing efficiency of vehicle windows, the present application proposes a vehicle window deicing method, structure, device, vehicle and storage medium.

[0048] Figure 2 This is a schematic diagram of a vehicle window deicing structure provided in an embodiment of the present application.

[0049] For example, Figure 2As shown, a vehicle is equipped with a blower 210 and a heater 220. The blower 210 has an air inlet 211 and an air outlet 212. One end of the heater 220 is connected to and communicates with the air outlet 212. To ensure that the heated airflow from the heater 220 is sprayed toward the vehicle windows, the other end of the heater 220 is positioned toward the vehicle windows. The heater 220 also includes a resistance wire. The heater 220 is installed behind the air outlet 212, allowing the airflow from the air outlet 212 to be heated by the heater 220 and sprayed toward the vehicle windows for de-icing.

[0050] Optionally, the blower 210 can be installed in the engine compartment so that the air intake 221 can draw in the air flow from the engine compartment; or when the blower 210 is not installed in the engine compartment, the air intake 221 of the blower 210 can be connected to the radiator of the engine compartment through a pipe, so that the air flow of the air intake 221 can come from the engine compartment in the vehicle 110, so that the waste heat in the engine compartment can be used to de-ice the windows, reducing the energy required by the heating device to heat the air flow out of the air outlet 212, thereby reducing the energy consumption required for de-icing the windows.

[0051] Optionally, the window may include Figure 1 The front windshield shown may also include one or more of the side door windows and the rear windshield window.

[0052] Exemplarily, a temperature control device 213 and a controller 214 are also connected to the blower 210 and the heating device 220. The temperature control device 213 can be used to collect the air flow temperature of the air inlet 211 and the internal temperature of the heating device 220, and the controller 214 can be used to control the opening and closing of the blower 210 and the heating device 220.

[0053] For example, the controller 214 may be configured to send an on instruction to a switch of the blower 210 , so that the switch of the blower 210 controls the blower 210 to turn on after receiving the on instruction.

[0054] For another example, the controller 214 may be configured to send a shutdown instruction to a switch of the heating device 220 , so that the switch of the heating device 220 controls the heating device 220 to be turned off after receiving the shutdown instruction.

[0055] The following combination Figures 3 to 5 The vehicle window deicing method provided in the embodiment of the present application is described in detail.

[0056] Figure 3 This is a flow chart of a vehicle window deicing method provided by an embodiment of the present application. Figure 1The vehicle 110 in the vehicle 110 is executed, or the electronic control unit (ECU) in the vehicle 110 is executed.

[0057] For example, Figure 3 As shown, the method 300 is applied to a vehicle, the vehicle includes a target deicing device, and the target deicing device includes Figure 2 The air outlet device and the heating device shown; the method 300 includes the following implementation process:

[0058] S310, detecting whether the vehicle windows are frozen.

[0059] For example, when the weather enters autumn and winter, the windows in the vehicle are prone to ice formation. In order to prevent the ice on the windows from affecting the driving safety of the vehicle, it is possible to detect whether there is ice on the vehicle windows when it is detected that the side door of the cab in the vehicle is opened, or when an unlocking signal for remotely opening the vehicle door is received, or when a remote start signal for the air-conditioning system in the vehicle is received.

[0060] In one possible implementation, the above-mentioned detection of whether the vehicle windows are frozen includes: capturing a target image of the vehicle windows through the vehicle's camera; if a foreign object is detected in the target image, obtaining the vehicle's outside temperature; if the outside temperature is less than a third temperature threshold, determining that the vehicle windows are frozen; if no foreign object is present in the target image, and / or the outside temperature is greater than or equal to the third temperature threshold, determining that the vehicle windows are not frozen.

[0061] The third temperature threshold may be used to represent the icing temperature of the vehicle window, that is, 0 degrees Celsius (°C).

[0062] Optionally, each window in the vehicle is equipped with a corresponding camera for capturing the current image of the window. For example, the camera corresponding to the front windshield is a front view module camera, the camera corresponding to the rear windshield is a rear view module camera, and the cameras corresponding to the side door windows are side view module cameras.

[0063] For example, the current image of the front windshield (which may be referred to as a "target image") can be captured by the front-view module camera, and the target image can be intelligently identified using an intelligent recognition device in the vehicle (e.g., an image recognition device) to identify whether there are foreign objects such as snowflakes, water vapor, or frost in the target image.

[0064] Furthermore, if there is a foreign object in the target image, the vehicle's ambient temperature (referred to as the "outside temperature") can be obtained and compared with a third temperature threshold. If the outside temperature is less than the third temperature threshold, it can be indicated that the vehicle's current outside temperature is below 0°C and there is foreign matter such as snow, water vapor, or frost on the vehicle windows. Therefore, the vehicle windows may be frozen due to the outside temperature being below 0°C.

[0065] For example, if it is recognized that there are no foreign objects such as snowflakes, water vapor or frost in the target image, it can be determined that there is no ice on the car window.

[0066] For example, if foreign objects such as snowflakes, water vapor or frost are identified in the target image, but because the outside temperature is greater than or equal to the third temperature threshold, it can be said that the current outside temperature of the vehicle is higher than 0°C and no ice layer will form on the windows. It can also be determined that there is no ice on the windows.

[0067] In this embodiment of the present application, when a foreign object is present in a vehicle window image, the determination of whether the vehicle window is iced is made in conjunction with the vehicle's outside temperature. This can avoid errors that would occur if a single window image or a single outside temperature were used to determine whether the vehicle window is iced. Therefore, combining image and temperature can improve the accuracy of determining whether a vehicle window is iced.

[0068] S320: If ice is detected on the vehicle window, the air outlet device and the heating device are controlled to operate so that the airflow ejected from the air outlet device is heated by the heating device and then ejected as hot airflow toward the vehicle window.

[0069] For example, if ice is detected on the vehicle windows, the air outlet device and the heating device included in the de-icing equipment in the vehicle can be controlled to work simultaneously, so that the air flow ejected from the air outlet of the air outlet device is heated by the heating device and then ejected as hot air flow toward the vehicle windows to de-ice the vehicle windows.

[0070] For example, if ice is detected on the car window, in order to facilitate the driver to drive the vehicle quickly, the window area where the driver observes the road condition information can be controlled to be de-iced. Figure 4 The road condition information includes but is not limited to lane information, vehicle speed information, traffic light information, and passing vehicle information.

[0071] Figure 4 It is a schematic diagram of another vehicle window deicing structure provided in an embodiment of the present application.

[0072] For example, Figure 4 As shown, Figure 4 The air outlet device and Figure 2 The air outlet device 210 shown in FIG is the same as that shown in FIG, and will not be described in detail here. Figure 4The air inlet of the heating device is equipped with a filter to prevent the gas from containing impurities and causing pipe blockage. Figure 4 The other end of the heating device (i.e., the air outlet of the heating device) is connected to and communicates with the pipeline 410. There are multiple branch pipelines on the pipeline 410, for example, pipeline A2, pipeline B2 and pipeline C2.

[0073] Among them, since the pipe 410 can transmit the hot air flow heated by the heating device to the vehicle window, when the air outlet of the heating device is connected to the pipe 410, the direction of the air outlet of the heating device can be not limited, that is, the air outlet of the heating device does not need to face the vehicle window, and can be determined according to the actual installation requirements of the heating device. The embodiment of the present application does not limit this.

[0074] Optionally, pipe 410, pipe A2, pipe B2 and pipe C2 can be selected as heat-resistant rubber hoses, and at least one layer of insulation layer can be wrapped around the outside of the pipes, so as to avoid the loss of air heat when transporting hot air flow, ensuring the stability of the hot air flow temperature; and to prevent the surrounding components of the pipes from being baked and damaged when transporting hot air flow, thereby ensuring the safety of the pipes when transporting hot air flow.

[0075] In addition, in order to facilitate the installation of the pipeline on the vehicle, the pipeline segments can be fixed to the interior of the vehicle body, for example, on the inner panel of the engine hood, by means of buckles 420 .

[0076] refer to Figure 4 Each branch pipe on the pipe 410 is provided with a corresponding nozzle, for example, pipe A2 corresponds to nozzle A3, pipe B2 corresponds to nozzle B3, and pipe C2 corresponds to nozzle C3. The number of branch pipes corresponds to the same number of nozzles.

[0077] For example, nozzles A3, B3, and C3 can spray hot air heated by the heating device to different areas of the vehicle window 430. For example, nozzle A3 sprays hot air corresponding to area A, nozzle B3 sprays hot air corresponding to area B, and nozzle C3 sprays hot air corresponding to area C.

[0078] It should be noted that the sum of the areas of region A, region B and region C is greater than or equal to the area of ​​the vehicle window 430 , that is, when nozzles A3 , nozzles B3 and nozzles C3 simultaneously eject hot air flows, the hot air flows can be sprayed toward any position on the vehicle window 430 .

[0079] Optionally, the jet openings of nozzle A3, nozzle B3 and nozzle C3 may all be set to be flat, which can increase the coverage area of ​​the hot air flow ejected from the nozzles and make the ejected hot air flow more uniform compared to a circular opening.

[0080] Optionally, there may be no branch pipe on the pipe 410. After the other end of the heating device is connected and communicated with the pipe 410, the hot air flow can also be transported to the corresponding nozzle through the pipe 410, so that the nozzle can spray the hot air flow toward the car window.

[0081] In one possible implementation, if ice is detected on the vehicle window, whether a target area in the vehicle window is frozen is detected; wherein the target area is the area of ​​the vehicle window where the driver observes road conditions; the above-mentioned control of the air outlet device and the heating device to operate so that the airflow ejected by the air outlet device is heated by the heating device and then ejected as a hot air flow toward the vehicle window, including: if ice is detected on the target area, controlling the flow rate of the hot air flow ejected by the target nozzle corresponding to the target area among the multiple nozzles to be greater than the flow rate of the hot air flow ejected by the non-target nozzles other than the target nozzle among the multiple nozzles; or, if ice is detected on the target area, first controlling the target nozzle to eject the hot air flow, and then controlling the non-target nozzle to eject the hot air flow until the target area is not frozen.

[0082] For example, if ice is detected on the vehicle window, the window area (which may be referred to as the "target area") where the driver observes lane information, vehicle speed information, traffic light information, and passing vehicle information may be detected to determine whether ice is present. For example, Figure 4 Area D shown.

[0083] Furthermore, if ice is detected in area D, the nozzles (which can be called "target nozzles") that eject hot air flows that can cover area D among nozzles A3, nozzle B3, and nozzle C3 can be obtained, that is, nozzle C3 is the target nozzle, and nozzles A3 and nozzle B3 are non-target nozzles. In addition, the flow rate of the hot air flow ejected by nozzle C3 can be controlled to be greater than the flow rates of the hot air flows ejected by nozzles A3 and nozzle B3, that is, the flow rate of the hot air flow ejected by nozzle C3 > the flow rate of the hot air flow ejected by nozzle A3, and the flow rate of the hot air flow ejected by nozzle C3 > the flow rate of the hot air flow ejected by nozzle B3. Alternatively, the flow rate of the hot air flow ejected by nozzle C3 can be controlled to be greater than the sum of the flow rates of the hot air flows ejected by nozzles A3 and nozzle B3, that is, the flow rate of the hot air flow ejected by nozzle C3 > the flow rate of the hot air flow ejected by nozzle A3 + the flow rate of the hot air flow ejected by nozzle B3.

[0084] Optionally, if ice is detected in area D, nozzle C3 may be controlled to eject hot air flow first, and then nozzle A3 and nozzle B3 may be controlled to eject hot air flow after area D is successfully de-iced.

[0085] In an embodiment of the present application, when ice is detected in the area of ​​the vehicle window where the driver observes road conditions (which can be called the "target area"), the flow rate of the hot air flow ejected by the target nozzle corresponding to the target area among the multiple nozzles can be controlled to be greater than the flow rate of the hot air flow ejected by the non-target nozzle other than the target nozzle among the multiple nozzles; or, the target nozzle is controlled to eject the hot air flow first, until the target area is not frozen, and then the non-target nozzle is controlled to eject the hot air flow, so that the target area in the vehicle window is de-iced first; thereby ensuring the driving safety of the vehicle during the de-icing process.

[0086] exist Figure 3 In the illustrated method 300, when ice is detected on the vehicle windows and the vehicle is not started, to prevent the vehicle from being unable to start normally due to battery power consumption during window de-icing, the obtained vehicle's remaining battery power can be compared with a preset battery power value. If the remaining battery power is greater than the preset battery power value, indicating that the remaining battery power after de-icing the vehicle windows is sufficient to meet the vehicle's starting requirements, the air outlet device and the heating device are then controlled to operate so that the airflow ejected by the air outlet device is heated by the heating device and then ejected as a hot air flow toward the vehicle windows to de-ice the vehicle windows. When vehicle start is detected, the air outlet device and the heating device are directly controlled to operate so that the airflow ejected by the air outlet device is heated by the heating device and then ejected as a hot air flow toward the vehicle windows to de-ice the vehicle windows. This approach not only prevents the vehicle from being unable to start normally due to battery power consumption during window de-icing, but also prevents the inefficient manual de-icing of the vehicle windows by the user by controlling the heating device and the air outlet device to automatically de-ice the vehicle windows. Therefore, based on the above solution, the de-icing efficiency of the vehicle windows can be improved while ensuring the normal start of the vehicle.

[0087] Optionally, after the above-mentioned control of the air outlet device and the heating device, in order to control the working state of the heating device, the air inlet airflow temperature of the air flow from the engine compartment of the vehicle in the air outlet device can be obtained; based on the air inlet airflow temperature, determine whether to control the heating device to stop heating.

[0088] For example, when the air outlet device and the heating device are controlled to operate, the temperature of the air flow sucked from the engine compartment by the air inlet of the air outlet device (which may be referred to as the "inlet air flow temperature") may be obtained. Whether to control the heating device to stop heating may be determined based on the inlet air flow temperature.

[0089] In the embodiment of the present application, since the airflow from the air outlet of the air outlet device is derived from the engine compartment of the vehicle, the residual heat in the engine compartment can be used to de-ice the vehicle windows, thereby reducing the energy required by the heating device to heat the airflow ejected by the air outlet device, thereby reducing the energy consumption required for de-icing the vehicle windows.

[0090] Furthermore, the above-mentioned determination of whether to control the heating device to stop heating based on the air inlet air flow temperature includes: if the air inlet air flow temperature is greater than a first temperature threshold, determining whether to control the heating device to stop heating; if the air inlet air flow temperature is less than or equal to the first temperature threshold, determining whether to control the heating device to stop heating based on the internal temperature of the heating device.

[0091] Among them, the first temperature threshold can be used to represent the set gas temperature for de-icing the car windows, for example, 20°C or 25°C. The set gas temperature is related to the thickness of the ice layer and the temperature outside the car, and this embodiment of the application is not limited to this.

[0092] For example, a temperature sensor located at the air inlet can be used to collect the air inlet temperature. If the collected air inlet temperature is 30°C, which is greater than a first temperature threshold of 20°C, it indicates that the air inlet temperature meets the set gas temperature for window de-icing. The air inlet flow can then be ejected directly onto the windows through the air outlet of the air outlet device to de-ice the windows without the need for a heating device. Therefore, the heating device can be controlled to stop heating (i.e., the air outlet device is operating, but the heating device is not operating), thereby reducing the energy consumption required for window de-icing.

[0093] For example, if the collected air inlet air flow temperature is 10°C, which is lower than the first temperature threshold of 20°C, it means that the air inlet air flow temperature cannot meet the set gas temperature for de-icing the windows, and the heating device needs to work (both the air outlet device and the heating device are working) to increase the air inlet air flow temperature so that the temperature of the heated hot air flow meets the temperature for de-icing the windows; and, in the process of the heating device heating the air inlet air flow temperature, in order to avoid excessive temperature increase, resulting in a large difference between the temperature of the hot air flow and the current freezing temperature of the windows, which poses a risk of the windows bursting, it can be determined whether to control the heating device to stop heating based on the internal temperature of the heating device.

[0094] In the embodiment of the present application, when the air inlet air temperature is greater than a first temperature threshold, it indicates that the air inlet air temperature meets the temperature requirement for de-icing the vehicle windows. Therefore, the heating device is no longer required to heat the air inlet air. Instead, the air outlet device can directly discharge the air inlet air toward the vehicle windows to de-ice the windows. Therefore, when the air inlet air temperature is greater than the first temperature threshold, the heating device is controlled to stop heating, thereby reducing the energy consumption required for de-icing the vehicle windows.

[0095] Furthermore, when the air inlet temperature is less than or equal to the first temperature threshold, it indicates that the air inlet temperature cannot meet the temperature requirements for window de-icing, and the heating device is required to increase the air inlet temperature. However, when the heating device is operating, the internal temperature is too high, which can pose a threat to the safety of the windows and the vehicle during the window de-icing process. Therefore, it is necessary to determine whether to control the heating device to stop heating based on the internal temperature of the heating device to ensure the safety of the windows and the vehicle during the window de-icing process.

[0096] Furthermore, the above-mentioned determination of whether to control the heating device to stop heating based on the internal temperature of the heating device includes: if the internal temperature is greater than a second temperature threshold, determining to control the heating device to stop heating; wherein the second temperature threshold is greater than the first temperature threshold; if the internal temperature is less than or equal to the second temperature threshold, determining to control the heating device to keep heating.

[0097] Among them, the second temperature threshold can be used to represent the safe temperature of the heating device, for example, 60°C or 65°C. The safe temperature is related to the model and installation location of the heating device, and the embodiment of the present application does not limit this.

[0098] For example, a temperature sensor installed inside the heating device can collect the internal temperature of the heating device. If the internal temperature is 70°C, which is greater than the second temperature threshold of 60°C, it indicates that the internal temperature of the heating device is too high. This may cause the temperature of the heated hot air flow to differ significantly from the current icing temperature of the vehicle window, posing a risk of window explosion. Alternatively, the excessive internal temperature of the heating device may cause the heating device to spontaneously combust, posing a safety threat to the vehicle. Therefore, it is necessary to control the heating device to stop heating (i.e., the air outlet device is operating and the heating device is not operating) to ensure the safety of the windows and the vehicle during the window de-icing process.

[0099] For example, if the collected internal temperature is 55°C, which is lower than the second temperature threshold of 60°C, it can be said that the internal temperature of the heating device is in a safe range, and when the air flow temperature at the air inlet is lower than or equal to the first temperature threshold, and the internal temperature of the heating device is lower than or equal to the second temperature threshold, in order to ensure the normal de-icing of the windows, it is necessary to control the heating device to keep heating, that is, both the air outlet device and the heating device are working.

[0100] In this embodiment of the present application, when the internal temperature of the heating device exceeds the second temperature threshold, it indicates that the internal temperature of the heating device is too high. To avoid a significant difference between the temperature of the heated hot air flow and the current icing temperature of the vehicle window, which could cause the window to burst; or the excessively high internal temperature of the heating device could cause the heating device to spontaneously combust, posing a threat to vehicle safety. Therefore, when the internal temperature of the heating device exceeds the second temperature threshold, the heating device is controlled to stop heating (i.e., the air outlet device operates, but the heating device does not operate), thereby ensuring the safety of the windows and the vehicle during the window de-icing process.

[0101] Furthermore, when the internal temperature of the heating device is less than or equal to the second temperature threshold, it indicates that the internal temperature of the heating device is within the safe range. When the air inlet temperature is less than or equal to the first temperature threshold and the internal temperature of the heating device is less than or equal to the second temperature threshold, the heating device is required to raise the air inlet temperature to a level sufficient for vehicle de-icing. Therefore, when the internal temperature of the heating device is less than or equal to the second temperature threshold, controlling the heating device to maintain heating ensures normal window de-icing, thereby improving window de-icing efficiency.

[0102] Optionally, after controlling the air outlet device and the heating device to operate in the above S320, the operating time of the air outlet device can also be obtained; every time the operating time reaches a preset operating time, the vehicle's wiper device is controlled to operate a preset number of times.

[0103] The windshield wiper device is used to spray water on the vehicle windows and / or scrape off ice on the vehicle windows. The windshield wiper device includes but is not limited to a windshield wiper.

[0104] Optionally, the preset working time and the preset number of times are obtained by actual vehicle calibration when the vehicle windows are iced. For example, the preset working time is 5 minutes and the preset number of times is 3 times. The preset working time and the preset number of times are respectively related to factors such as the vehicle window area and the vehicle window material, and are not limited to these factors in the comparison of the embodiments of the present application.

[0105] For example, after controlling the air outlet device and the heating device to work, in order to avoid directly starting the wiper device when the wiper device is frozen, which may cause damage to the wiper, the air outlet device and the heating device can be operated for a period of time, and the car windows can be de-iced for a period of time, and then the wiper device can be controlled to work. Moreover, since the air outlet device is always in working state, the working time of the air outlet device can be obtained, and when the working time reaches the preset working time of 5 minutes, it means that the car windows have been de-iced for a period of time, so that the ice layer can play a lubricating role after melting, and avoid sharp ice crystals from damaging the wiper device and the car windows. Then, the wiper device in the vehicle can be controlled to swing a preset number of times (for example, 3 times) to make the wiper device spray glass water on the car windows, clean the dirt on the car window surface, and / or scrape off the ice on the car windows to de-ice the car windows.

[0106] Optionally, when the wiper system finishes operating, it can capture a current image of the de-iced vehicle window and detect whether foreign objects are still present in the current image. If foreign objects are still present in the current image, it can be re-determined whether the vehicle is started, and the collected operating time of the air outlet device can be reset to 0, and the collection can be repeated. That is, the number of times the vehicle is re-determined whether it is started is the same as the number of times the operating time of the air outlet device is collected. Alternatively, if the current image is detected to be free of foreign objects, indicating that the window de-icing is complete, the air outlet device and the heating device can be controlled to stop operating.

[0107] In an embodiment of the present application, when it is obtained that the working time of the air outlet device reaches the preset working time, it means that the vehicle windows have been de-iced for a period of time, so that the ice layer can act as a lubricant after melting, thereby avoiding sharp ice crystals from damaging the wiper device and the vehicle windows, and directly starting the wiper device when the wiper device is frozen, which may cause damage to the wiper, thereby ensuring the safety of using the wiper device when the vehicle windows are frozen.

[0108] Figure 5 This is a flow chart of another vehicle window deicing method provided in an embodiment of the present application.

[0109] For example, Figure 5 As shown, the method 500 includes the following implementation process:

[0110] S501, collecting a current image of a vehicle window through a camera of the vehicle.

[0111] For example, when it is detected that the driver's cab side door of the vehicle is opened, or when an unlock signal for remotely opening the vehicle door is received, or when a start signal for remotely starting the air-conditioning system in the vehicle is received, the current image of the front windshield (i.e., the above-mentioned target image) can be captured by the front-view module camera.

[0112] S502: Determine whether there is a foreign object in the current image. If not, execute S503; if so, execute S504.

[0113] For example, the image recognition device in the vehicle can intelligently recognize the current image of the front windshield captured by the front view module camera to identify whether there are foreign objects such as snowflakes, water vapor or frost in the current image.

[0114] S503: The air outlet device and the heating device do not work.

[0115] For example, if it is determined that there are no foreign objects such as snowflakes, water vapor, or frost in the current image, it can be determined that there is no ice on the car window. Therefore, there is no need to control the air outlet device and the heating device to operate, that is, the air outlet device and the heating device are not operated.

[0116] S504: Detect whether the outside temperature of the vehicle is lower than 0° C. If so, execute S505; if not, execute S503.

[0117] For example, if foreign objects such as snowflakes, water vapor or frost are identified in the current image, the outside temperature of the vehicle can be obtained and compared with 0°C to determine whether the outside temperature is lower than 0°C (that is, the third temperature threshold mentioned above).

[0118] S505: Determine whether the vehicle window is frozen.

[0119] For example, if the outside temperature is lower than 0°C and there is foreign matter such as snow, water vapor or frost on the vehicle window, the vehicle window may be frozen due to the outside temperature being lower than 0°C, and the vehicle window is determined to be frozen.

[0120] For example, if foreign objects such as snowflakes, water vapor or frost are identified in the target image, but because the temperature outside the vehicle is greater than or equal to 0°C, the snowflakes, water vapor or frost will not form an ice layer on the vehicle window, S503 can also be executed, that is, the air outlet device and the heating device do not work.

[0121] S506: Determine whether the vehicle is started. If not, execute S507; if so, execute S509.

[0122] For example, if ice is detected on the vehicle windows, in order to ensure normal starting of the vehicle, the vehicle's power switch status and / or engine status can be obtained to determine whether the vehicle is started based on the vehicle's power switch status and / or engine status.

[0123] Optionally, if the vehicle's power switch is in the "ON" position and / or the engine enters the running state, it can be said that the vehicle is started. Conversely, if the vehicle's power switch is in the "OFF" position and / or the engine has not entered the running off state, it can be said that the vehicle is not started.

[0124] S507: Obtain the remaining power of the vehicle.

[0125] For example, if it is detected that the windows are frozen and the vehicle is not started, in order to avoid the problem that the vehicle cannot meet the power required for normal starting due to battery power consumption when de-icing the windows, the remaining power of the vehicle (State of Charge, SOC) can be obtained first.

[0126] S508: Determine whether the remaining power is greater than a preset power value. If so, execute S509; if not, execute S506.

[0127] The preset power value may be used to represent the minimum power value required for starting the vehicle, for example, 60%.

[0128] For example, if ice is detected on the vehicle windows and it is determined in S506 that the vehicle is not started, the acquired SOC may be compared with a preset power value (eg, 60%) to determine whether the SOC is greater than 60%.

[0129] S509, controlling the air outlet device and the heating device to operate.

[0130] For example, if the SOC is greater than 60%, it means that the remaining power after de-icing the windows can meet the vehicle's starting requirements, so that the air outlet device and the heating device can be controlled to work simultaneously, so that the air flow ejected from the air outlet of the air outlet device is heated by the heating device and then the hot air flow is ejected toward the windows to de-ice the windows.

[0131] For example, if the SOC is less than or equal to 60%, it can be indicated that the remaining power after the windows are de-iced cannot meet the vehicle starting requirement. In order to ensure normal starting of the vehicle, it can be determined in S506 whether the vehicle is started.

[0132] For example, if ice is detected on the vehicle windows and it is determined through S506 that the vehicle is started, the air outlet device and the heating device can also be controlled to work simultaneously, so that the air flow ejected from the air outlet of the air outlet device is heated by the heating device and then ejected as hot air flow toward the vehicle windows to de-ice the vehicle windows.

[0133] For example, if ice is detected on the vehicle windows and it is determined in S506 that the vehicle has not started, to ensure normal vehicle startup, the vehicle can be controlled to start normally first. After the vehicle starts, the air outlet device and the heating device can be controlled to operate simultaneously so that the airflow ejected from the air outlet of the air outlet device is heated by the heating device and then ejected toward the vehicle windows to de-ice the windows. In other words, the prerequisite for controlling the operation of the air outlet device and the heating device is that the vehicle can start normally. This can avoid the phenomenon of the vehicle not being able to start normally due to battery power consumption during window de-icing, thereby improving the de-icing efficiency of the vehicle windows while ensuring normal vehicle startup.

[0134] It's important to note that the amount of power required for the air vent and heater to operate depends on the vehicle's powertrain. Specifically, the amount of power required for a purely electric vehicle's air vent and heater to operate is greater than the amount required for a hybrid or fuel-powered vehicle. However, regardless of whether the vehicle is powered by pure electric, hybrid, or fuel, the air vent and heater require electrical energy to operate. Therefore, to ensure that the remaining power after de-icing the windows is sufficient to start the vehicle, the vehicle's SOC must be determined.

[0135] S510 , determining whether the temperature of the air flow from the air inlet of the air outlet device originating from the engine compartment is greater than 20° C. If not, executing S511 ; if so, executing S514 .

[0136] For example, when controlling the operation of the air outlet device and the heating device, the air inlet air flow temperature can be collected by a temperature sensor arranged at the air inlet of the air outlet device, and it can be determined whether the air inlet air flow temperature sucked into the engine compartment by the air inlet of the air outlet device is greater than 20°C (that is, the above-mentioned first temperature threshold).

[0137] S511, determine whether the internal temperature of the heating device is greater than 60° C. If not, execute S512; if so, execute S514.

[0138] For example, if the collected air inlet air flow temperature is 10°C, which is less than 20°C, it means that the air inlet air flow temperature cannot meet the set gas temperature for de-icing the car windows, and the heating device needs to work (both the air outlet device and the heating device are working) to increase the air inlet air flow temperature so that the heated hot air flow temperature meets the temperature for de-icing the car windows.

[0139] Furthermore, in the process of the heating device heating the air flow temperature at the air inlet, in order to avoid excessive temperature increase, which may cause the temperature of the hot air flow to differ too much from the current freezing temperature of the car window, thereby posing a risk of the car window bursting, it is possible to determine whether the internal temperature of the heating device is greater than 60°C (that is, the above-mentioned second temperature threshold).

[0140] S512, controlling the air outlet device to keep working and the heating device to keep heating.

[0141] For example, if the internal temperature of the heating device is less than or equal to 60°C, it can be said that the internal temperature of the heating device is in a safe range, and when the air flow temperature at the air inlet is less than or equal to 20°C and the internal temperature of the heating device is less than or equal to 60°C, in order to ensure the normal de-icing of the windows, it is necessary to control the air outlet device to keep working and the heating device to keep heating to ensure that the de-icing of the windows can be carried out normally.

[0142] S513: After 5 minutes, the wiper device is started to spray glass water onto the vehicle window, and the wiper device is controlled to perform the wiper action on the vehicle window 3 times.

[0143] For example, after controlling the heating device to maintain heating, the working time of the air outlet device can be obtained, and every time the working time reaches 5 minutes (i.e. the above-mentioned preset working time), it indicates that the vehicle windows have been de-iced for a period of time, so that the ice layer can act as a lubricant after melting, preventing sharp ice crystals from damaging the wiper device and the vehicle windows, and then the wiper device in the vehicle can be controlled to spray glass water onto the vehicle windows to clean the dirt on the surface of the vehicle windows; and the wiper device can be controlled to perform the wiping action on the vehicle windows 3 times (i.e. the above-mentioned preset number of times) to scrape off the ice on the vehicle windows.

[0144] S514, controlling the heating device to stop heating, while the air outlet device keeps working.

[0145] For example, if the air inlet temperature measured in S510 is 30°C, which is greater than 20°C, the air inlet temperature meets the set temperature for window de-icing. The air inlet can be directly ejected onto the windows through the outlet of the air outlet device to de-ice the windows without the need for a heating device. Therefore, the heating device can be controlled to stop heating while the air outlet device remains operational, thereby reducing the energy consumption required for window de-icing.

[0146] For example, if the internal temperature of the heating device detected in S511 is 70°C, which is greater than 60°C, it indicates that the internal temperature of the heating device is too high. This may cause the temperature of the heated hot air flow to differ significantly from the current icing temperature of the window, posing a risk of window explosion. Alternatively, the excessive internal temperature of the heating device may cause the heating device to spontaneously combust, posing a safety threat to the vehicle. Therefore, it is necessary to control the heating device to stop heating and keep the air outlet device operating to ensure the safety of the windows and the vehicle during the window de-icing process.

[0147] S515 , collecting an image of the vehicle window after being cleaned by the wiper device through a camera of the vehicle.

[0148] For example, after controlling the wiper device to spray glass water onto the vehicle window to clean the dirt on the surface of the vehicle window; and controlling the wiper device to perform the wiping action on the vehicle window three times to scrape off the ice on the vehicle window, the vehicle's camera can collect the cleaned window image again.

[0149] S516: Determine whether there is a foreign object in the vehicle window image. If not, execute S517; if so, execute S506.

[0150] For example, the vehicle's camera may collect the cleaned window image again to identify whether there are foreign objects such as snowflakes, water vapor or frost in the window image.

[0151] S517, controlling the air outlet device and the heating device to stop working.

[0152] For example, when the wiper device finishes working, if it is detected that there is no foreign matter in the window image, it means that the window is de-iced successfully, and the air outlet device and the heating device can be controlled to stop working.

[0153] Optionally, when it is detected that the driver's cab side door is locked, or when a locking signal for remotely opening the vehicle door is received, or when a shutdown signal for remotely opening the air-conditioning system in the vehicle is received, it indicates that the vehicle is currently turned off, and the air outlet device and the heating device can also be controlled to stop working.

[0154] Alternatively, if foreign matter is detected in the window image, it indicates that the window de-icing is unsuccessful, and S506 can be executed again to determine whether the vehicle is started, and the collected working time of the air outlet device is reset to 0 and collected again.

[0158] Figure 6 It is a structural schematic diagram of the vehicle window deicing device provided in an embodiment of the present application.

[0159] For example, Figure 6 As shown, the device 600 is configured in a vehicle, the vehicle includes a target deicing device, and the target deicing device includes an air outlet device and a heating device; the device 600 includes:

[0160] A detection module 610 is used to detect whether the vehicle windows are frozen;

[0161] The control module 620 is used to control the air outlet device and the heating device to operate if ice is detected on the vehicle window, so that the air flow ejected by the air outlet device is heated by the heating device and then ejected as hot air flow toward the vehicle window.

[0162] In one possible implementation, the control module 620 is further used to: obtain the air inlet airflow temperature of the air flow from the engine compartment of the vehicle in the air outlet device; and determine whether to control the heating device to stop heating based on the air inlet airflow temperature.

[0163] In one possible implementation, the control module 620 is also used to: if the air inlet air flow temperature is greater than a first temperature threshold, determine whether to control the heating device to stop heating; if the air inlet air flow temperature is less than or equal to the first temperature threshold, determine whether to control the heating device to stop heating based on the internal temperature of the heating device.

[0164] In one possible implementation, the control module 620 is also used to: if the internal temperature is greater than a second temperature threshold, determine to control the heating device to stop heating; wherein the second temperature threshold is greater than the first temperature threshold; if the internal temperature is less than or equal to the second temperature threshold, determine to control the heating device to keep heating.

[0166] In one possible implementation, the hot air flow heated by the heating device is ejected toward the vehicle window through multiple nozzles in the target deicing device, and the multiple nozzles correspond to different areas of the vehicle window. The detection module 610 is further configured to: if ice is detected on the vehicle window, detect whether a target area of ​​the vehicle window is frozen; wherein the target area is the area of ​​the vehicle window where the driver observes road conditions;

[0167] In one possible implementation, the control module 620 is specifically used to: if ice is detected in the target area, control the flow rate of the hot air flow ejected by the target nozzle corresponding to the target area among the multiple nozzles to be greater than the flow rate of the hot air flow ejected by the non-target nozzles other than the target nozzle among the multiple nozzles; or, if ice is detected in the target area, first control the target nozzle to eject the hot air flow, and then control the non-target nozzle to eject the hot air flow until the target area is not frozen.

[0168] In one possible implementation, the detection module 610 is specifically used to: capture a target image of the vehicle window through the vehicle's camera; if a foreign object is detected in the target image, obtain the vehicle's outside temperature; if the outside temperature is less than a third temperature threshold, determine that the vehicle window is frozen; if there is no foreign object in the target image, and / or the outside temperature is greater than or equal to the third temperature threshold, determine that the vehicle window is not frozen.
